True black levels and colour depth
QD-OLED technology pairs a blue self-emitting layer with a quantum dot layer. This delivers deep blacks and wide colour coverage. We see 99% DCI-P3 gamut for rich, accurate hues. In practice, games and films look lifelike with strong contrast.
Fluid motion with rapid response
A 240 Hz refresh and 1 ms response time reduce ghosting. VESA Adaptive Sync support helps keep frames smooth. The panel’s 0.03 ms GtG rating further cuts blur. So fast-paced titles render cleanly with no lag.
Ergonomic stand and tidy setup
The adjustable stand offers height, tilt, swivel, and pivot. You can set the exact viewing angle for comfort. A frameless design keeps focus on the image. Also, the internal power supply simplifies cable management.
Connectivity for PC and console
Two HDMI 2.1 ports and one DisplayPort 1.4a are included. USB Type-C with DisplayPort Alt Mode supports video and data. A built-in USB hub adds two Type-A ports and one Type-B upstream. Headphone out is available for audio.
OLED care and long-term reliability
MSI OLED Care 2.0 helps reduce burn-in risk. It uses pixel shift, panel protect, and static screen detection. These features run in the background to preserve the panel. We recommend using them for peace of mind.
